Representer Point Selection for Explaining Regularized High-dimensional Models

no code implementations31 May 2023 Che-Ping Tsai, Jiong Zhang, Eli Chien, Hsiang-Fu Yu, Cho-Jui Hsieh, Pradeep Ravikumar

We introduce a novel class of sample-based explanations we term high-dimensional representers, that can be used to explain the predictions of a regularized high-dimensional model in terms of importance weights for each of the training samples.

Faith-Shap: The Faithful Shapley Interaction Index

1 code implementation2 Mar 2022 Che-Ping Tsai, Chih-Kuan Yeh, Pradeep Ravikumar

We show that by additionally requiring the faithful interaction indices to satisfy interaction-extensions of the standard individual Shapley axioms (dummy, symmetry, linearity, and efficiency), we obtain a unique Faithful Shapley Interaction index, which we denote Faith-Shap, as a natural generalization of the Shapley value to interactions.

Order-free Learning Alleviating Exposure Bias in Multi-label Classification

1 code implementation8 Sep 2019 Che-Ping Tsai, Hung-Yi Lee

In this paper, we propose a new framework for MLC which does not rely on a predefined label order and thus alleviates exposure bias.

Completely Unsupervised Speech Recognition By A Generative Adversarial Network Harmonized With Iteratively Refined Hidden Markov Models

no code implementations8 Apr 2019 Kuan-Yu Chen, Che-Ping Tsai, Da-Rong Liu, Hung-Yi Lee, Lin-shan Lee

Producing a large annotated speech corpus for training ASR systems remains difficult for more than 95% of languages all over the world which are low-resourced, but collecting a relatively big unlabeled data set for such languages is more achievable.

Transcribing Lyrics From Commercial Song Audio: The First Step Towards Singing Content Processing

no code implementations15 Apr 2018 Che-Ping Tsai, Yi-Lin Tuan, Lin-shan Lee

Spoken content processing (such as retrieval and browsing) is maturing, but the singing content is still almost completely left out.
